A Christian doctor and transgender model came to blows in a heated debate over gender - and This Morning fans were completely divided by their argument.

Dr David Mackereth was sacked from his job in the NHS after he refused to refer to trans people by their preferred gender pronoun, and came on the show to defend his position, believing doctors should be able to have a conscience and beliefs which inform their decision-making.

But he was joined on the couch by model Munroe Bergdorf, who tried to explain to the doctor that sex and gender were different, and believed the doctor should have been removed from his post.

Dr David told stand-in presenters Ruth Langsford and Eamonn Holmes: "When I use gender I use it the same as sex... I believe God made mankind male and female and it’s extremely important as a generation to uphold this truth."

Later, he said he believed transgenderism is "bringing the wrath of God on our generation" and believed if everyone who followed their conscience was sacked, the NHS would be empty.

But Munroe fought back with her fiery message, saying it was good he was fired and should have been for his actions.

She said: "Surgery doesn’t have a bearing on how far someone is along their transition... his job is to help people and he’s not doing his job if he’s not helping people."

Munroe also said trans people are most vulnerable and need to be believed before surgery, and she insisted her views have been proven in science.

She continued: "It’s recognised within medical practitioners... there is the process and how you help trans people but this guy is saying, 'no, I’m not helping people.'

"If these are his religious beliefs he should have lost his job - you’re a public servant, you should be helping people."

Munroe said the change is done to the body to align it with who a trans person has always been, but Dr David said he believed it's impossible to change a person's sex as it has been assigned by God as male or female.

The debate divided viewers, with many taking to social media to give their views.

One person who disagreed with the doctor said: "'As a Christian' it makes me very sad to see the close minded view of some people on @itvthismorning.

"I don't feel that what I or anyone else believes in, should be used as a reason to stop people being who they truly are!

Others backed the doctor, however, with one saying: "So agree with the doctor thismorning your make [male] or female at birth full stop.. if you want to be a boy or girl it's up to you but don't expect anyone else too."

A poll held by the show said 53% agree with doctor, but clearly it is a close divide between people watching at home.
